Millwall boss Neil Harris was pleased with his team's comfortable 3-0 pre-season friendly victory over Granada Club de Futbol at The Den on Saturday afternoon.
Goals from Jed Wallace, Shaun Williams and Aiden O'Brien eased The Lions to success against their Spanish counterparts and Harris claimed that certain performances have given him "a lot to consider" ahead of next Friday's Sky Bet Championship opening game at Nottingham Forest.
"I thought we looked fit, strong, organised and disciplined," he said. "Our use of the ball was really strong at times and we looked good in possession against a possession-based team that wanted to play through us.
"The Championship will be a really good League this year, full of great players that have international experience. We're going to have to have all those traits we showed today in abundance throughout the season, starting next week at Forest.
"We have to impose ourselves on teams - I thought today, we imposed our gameplan on Granada.
"I thought it was a really good performance. There was some outstanding performances collectively and individually - it's given me a lot to consider between now and next Friday night."
